Ternary Plots, 3D - Space

This type of ternary graph offers a distinctive method of representing 3D scatterplot data through the use of an X-Y-Z plane (defined via a triangular coordinate system) positioned at a user-selectable level of the vertical V-axis (which "sticks up" through the middle of the plane). The level of the X-Y-Z plane can be adjusted in order to divide the X-Y-Z- space into meaningful parts (e.g., featuring different patterns of the relation between the three variables).
